IOAD-DISCHARGN G CARV Appmauon and July 1o, 1925. serai No. 42,635.

My invention relates to improvements in load discharging cars 'and especially of that type adapted to discharge ballast centrally of the rails or to either side thereofor to 5 both sides and center simultaneously.

One object of my invention is to ada t a car of thetype indicated so that it w11 s1- multaneously place ballast in the center of the track and at the sides thereof in'such a manner as to obviate flooding the rails and ,which willy be simple in design.

A second Object of the invention 1s to pro-A vide a car having a pair ofhoppers, each. disposed to one side o the center of the car,

15 which will be adapted to discharge the contents of the two hoppers simultaneously through a central opening in such armanner that the load passing through the odpenmgs of the respective hoppers will be eflected centrally of the rails and'l issue as a unit flow forming a pile of ballast between the rails, so limited inlsze that the sloping sides there-l of will atall times be confined between the rails and below the tops thereof.

A third objectof the inventionl is to so adapt the movable parts of a car of the indicated type that it will be possible to deposit the maxlmum size heap at the time of mm1- mum door Opening and thereafter as the flow of ballast increases to provide for a decrease in the sizeof the hea I. I t

Itis also an'object of the mvention to defiect the ow of material from two `adjacent hoppers through a narrow space disposed` centrally of the rails and defined by the free edges vof movable doors so that the .discharging material from the respective' hoppers will commence'to flow freely only when the respective doors are in suchposition that they will positively limit the sloping, sides lof the pile of material to the extent that the base ofthe said pile will bevconfineld between rails and below' the topsthereof.l .y

v Another object of the invention is to provide a simplefcanfotthis character which may discharge to...both sides of the car andv to theeenter simultaneously, and to so adapt' vthe parts thateach ofthe discharge open- -ingsmav be operated at'f'the same time but independently of 'each other and the extent of openinglvariedlin any Onelwithout laiecting the operation or degree :of opening of any of the other discharge openings.

Still another object of the invention is to Vsfults obtained under various .d0oropemngs ..-Fxgure 8 is a diagran'xmatic provide a car adapted for ,center and side ballasting wherein the parts are .so proportioned and disposed that sections ofv the flooring of the car will of themselves be Suli cient to control the sloping sides ofthe piles Aof ballast so as to keep the same free of the rails thereby dispensing with batlie plates, extensions or other accessories on the swinging ed es of the door, such as would ord1- narily e used for the purpose of detlecting lading beyond a discharge opening.

A more specific object of the invention is' to guardagainst. excessive overflow of material at the endsof the doors whereby tho ballast left by a discharging moving car embodying my improvements will be of such proportions thatlthe truck to move freely over the same.

My invention also resides in certain other featuresof construction such as will be more fully pointed out hereinafter andtclaimed.

In said drawing, Figure 1 is a side elevational view of/ a ments incorporated therein, the left hand half portion of the car having the outside walls removed for vthe purpose of better' illustrating the interior'arrangement ofthe parts.I Figure 2 is a detached plan view on an enlarged scale fof one of the inner Hoor doors.` Figure 3 ijs a planY vieweof the car having the flooring broken away: in the left hand portion of thetigurelwliigure'fl is a transverse sectional` view takenthrough the lower portion ofthecar and Ona line cor`- responding substantially to the'line 4 4 of, Figure 1. l Figure 5 is a transverse sectional view taken through Vthe A'hoppe'rind on a linecorresponding' substantially to the line 5-5 of lFigure 1, the left hand section of the carfbeingtaken as facing theI end of the hopper and therght-hand portion as facing parts will be able car having/my improvef the center cross-beam.

The transverse walls D includes sloping floor plates 19 each having vertically depending portions 20-20 constituting one ofthe end walls of the air of transversely alined hopper sections G, saidfsloping floor plates being secured to and supported by a transversely extending beam '21. Each convertible floor section "E is pivotally mounted on hinge brackets 22 carried by the corresponding beam 21 and -is adapted to form, in one position, a continuation of the sloping floor sheet 19 and, in another osition, a portion of a level floor substantially in alinement with the top of the center sill hood 16. Each fixed door section F includes a floor sheet 23 extending transversely across the car.

TheI said doors are hingedly mounted on theshaft 28 by means of a butt hingearrangement formed of a plurality of longitudinally extending plates 31---31Il formed with hinge eyes and secured to each of the doors, the hinge portions 31-31 on the outer door 25 being' alternatedy with the corresponding. hinge portions of the adjacent door 24 thereby providing a continnous sealing hinge joint throughout'fthe length of the hoppers. Each 'of the doors A. "24 and 25 is preferably adapted to extend continuously beneath the central cross Vbeam H and for an appreciable distance beyond each vertical end hopper-Wall 2.0' at the r'e" spective ends of the longitudinal hoppers. The transverse baille plateszJ--Jare formed IUD to extend from side to side of the car and are disposed adjacent vthe ends of the respective `doors 24 and 25, said bafile'plates being' preferably formed of two late sections 32 and 33 overltp'pingly joine 'at the center of the car as in lica'ted at 34 and braced to the center-sill by a longitudinal brafcc 35 and to the res ective sides of the car' by gussets '36'-36.v aid'baliie plates are spaced a preciably from/ the vertical hopper end wa s and maintained in fixed relation thereto by spacing Amembers 137 which are Asecured to said baffle l plates are aiiged vat 37 Ito conform to the sloping floor 19 of the fixed end floor portion D and are extended outwardly beyond the side edges of the respective doors 24 and 25 and downwardly beyond the pivotal cen.- ters `of the said doors.

A V-shaped arrangement of doors to discharge the entire load toether side offthe lates and wall 20. Said baillev car orcentrally of the lrails is, broadly, 13

` the lhop 'rs arel disposed at .such a distance abovevt rail that the inner doors are intercepted by the lower portion of the center sill 101 vand the free A'edges of said inner doors are s'oA spaced from-each otherthat the material discharging between the free edges of the inner doors will issue in two .separate streams throughout the greater part of the movement-of the doors and the material 'does not merge into a unit stream .until the doors are nearly fully opened." To more clearly bring out the improvements of the presenty invention as compared with the prior'art and said patent specified with the rails added to show the relation of parts, I have added to Figure 9, to exactly the same scale as the rest' of the car shown my said prior patent, the rails'102and a/pile 'of lading indicated by conventional dotted lines 1mi-103, Va pile of ballast with the sides thereof` sloping on a ratio of 11/2 to l base to height ratio which is an accepted standard ratio lfor ballast. It will be: noted that the base of said pile is confined between the rails and below'the'tops thereof. As will seen by reference to said Fig.'9, the inner doors 100, when opened to '.formla continuation of the outer doors v104, have their free edges adjacent ,the slo 'ing sides 103 of the pile as above' defined, best results in ballasting it is desirable that the doors operate to'limlt the 'heap of ballast and maintain the same away from the rails during substantially the entire range of movement of thedoorfduringiwhich the material flows freelyifrom vthe car. It is obvious that the pile would have a lwider base and its apex hxgherj'if the doors 10() were held in any higher position than that shown and while permitting discharge so that the rails would be flooded.

In the present invention I overcome the tendency to ilood the rails by so (proportioning the parts in relation-to the rails and so disposing the adjacent hoppers relatively to each other and to the rails that the material from the pair 'of inner doors 24--24 will only commence to liow freely when the doors arev in a vposition to control the` lading and'- tudinally by beam members 138 and'39 Thefdoors 24 and.25"are` rigidied longi-v respectively disposed adjacent ,the hingeA and*4 free edgesof the doors and said doors are further braced transversely by a series of 'I braces as indicated at 40 and 41 The marut in order to' derive the ginaliedge'of'each inner door is depressed 4 ordeflected to present, as at 42, a suitable rigidifying means or ange lfor the'edge of the door, said flange being preferably formed to` extend at an appreciable angle tothe main plane of the door. Said flange 42,

when" the door is in closed position, v'seats beneath the outstanding flange 18 of the-` adjacent centersllmember 17. When the said inner door 24 is in closed position, it extends from the lowermost portion of the center sill at an. angle of approximately 40 degrees from the horizontal lane and oper` ates to direct lading to its adjacent discharge openin s. Said inner doors 24-24, as they swing ownwardly to'dischar e centrally of the rails,l have their free edgges approach relatively to e'ach other until l*such time as the main portions of the doors are in a substantially horizontal'positon at which time v.the distance between the free edges -of the A respective doors, as indicated at a in Fig. 7, will be-less than the opening between each door and corresponding center sill, as indicated' at WJ. Therefore, the lading discharging through the two larger. openings b will be deflected centrally of the car and merge andvissue as a unit stream of small proportions and the danger of flooding the rail will be obviated because the free flow of material between such central opening rious figures is shown in relation to the rail or truck parts in the position occu ied by an empty car but when such car is oaded the lsprings deflect and consequently the body under load would be nearer the rail and ballast pile by a distance equal to approximately the distance c which still further insures thebase of the pile being confined to points below the rail'tops. As the opening movement of the inner doors increases from the horizontal position and the distance a widens, increasingr the flow vof material, the base of the pile of material decreases as will be indicated by reference are indicated by lines 44, 45 and 46, corresponding to various degrees of door opening. In order to insure against flooding of thc t'o Fig. .7 wherein various degrees of heapfrails during ballastingl it is 'essential that excessive iowof ballast at the ends of the doors should be guarded against and to this end the baliie plates .I are disposed at each end of the doors and the res active doors extend continuously beneath t e crossbcamf '-,I'from one baille J to the other bale J at the opposite, ends of the hopper. Each swing downwardly from their inclined po- -`The inner doors 24 are raised an baille plate is extended downwardly a. suiicient distance below the axle to limit the heap of ballast so that the axle L will readily pass over the same.- Similarly the heap of ballast at the side of the car may be limited as indicated at .47 to permit the journal box N to pass over the same by positioning the side doors as indicated` in igure 7. Reference to 'Fig 8 indicates the outline of the ballast deposited between the rails when the free edges of the respective inner doors are positioned so that the said free edges coincides substantially with the lower margin ot' the baille plates J. A slope for tliedoors of 40 degrees from the horizontal plane is particularly eliicient inasmuch as it provides a plane on which lading of average density will readily iiow and also provides an opening, when the door is opened, which will prevent arching f the lading above the door inasmuch *as the horizontal distance al is slightly greater than the vertical distance e as will be seen by reference to Fig. 7. It will be noted that the hinge point 28 of the inner doors is substantially on a level with the top of the ballast heap; and as said inner doors sition as a portion of thecar' floor to the substantially horizontal position and thereafter to an inclined osition in continuation of Athe plane of t e outer doors, I am enabled to control the flow of ballast in any position with only so-much of door asis actuall necessary 'to bridge the space in-' termediate the lowermost part of the center sill `and the hinge of the door and in this manner avoid the use of cumbersome and heavy extensions or baies on the doors to deflect the material centrally of the'rails and away from the hopper openings,

lowered in unison by means of flexible connections 48v winding on an operating shaft 49 disposed between the' center sills, said shaft 49 being rotated by means of a cross shaft 50, said shafts 49 and 50 being operatively y gusset 'plates 36.

connected by worm and gearing 51-prefer ably disposed in a housing 52. Said cross shaft is disposed rearwardly of the battle plates J. and operated from either end thereof by means of shaft rotating means shown conventionally at 53, the shaft being supported at its outer ends by the Each outer door 25 is adapted to be operated independently of the other outerV door or of the innendoors 24. The operation of each of said doors is through the medium of iexible lconnections 54 winding on a longitudinal shaft 55, each shaft being mounted adjacent the free edge of the door and supported fromthe center crossbeam by means of a bracket 56 and at the ends of the doors by a bracket 57 and worm gear lhousing 58 respectively carried by baille plates J at the ends of said door. Ihe operation of each longitudinal shaft is ef- Jected 4by a short transverse shaft 59, said shafts being operatively connected by means of worm and gearing shown conventionally at 60 mounted in said housing 58. Each shaft 59 extends through the corresponding gusset plate 36 and rotating and locking means indicated conventionally at 6l are mountedoutwardly of said plate.

The flexible connections 48 and 54 for the respective doors 24 and 25 yare disposed in the plane of said doors passing through perforations 62 formed therein and the direction of pull on the said iiexible connections is reversed by. means of sheaves 63 over -whicli the said connections pass. Three flexible connections per door are preferably used, there being one extending through the center crossbeam H and at each end of the door, the latter extending between the baffle plates J and the adjacent, vertically depending hopper wall portion 20.

'llie arrangement of door operating mechanisms thus permits the operation of the center and both side doors simultaneously and as any one of said set of doors may be operated without atl'ecting the extent of opening or degree of angularity of any of the other sets of doors three operators may ballast from one car without either affecting the work of theothers.

It will thus be noted that the disposition of operating shafts and operating -mechanisms rearwardly of the battle plates protects the same from damag'eas well asinsures the safety of the operatbr against falling boulders which wouldnormally flow over the edgesof the door. Furthermore, the disposition of the partsl which provide perfect control over the discharging lading and automatically limit the iow'of the discharging ballast liowing through the center doors render the operation of a car having my improvements therein a very lsimple matter, as even if the operator shouldl open .the doors to the full extent, the rails will not beYflooded.
